Program generator for branching questionnaire

ABSTRACT

A COMPUTER SYSTEM IS PROVIDED, AS RREPRESENTED BY FIG. 3, FOR AUTOMATICALLY GENERATING, IN RESPONSE TO A SPECIFIED TREE-STRUCTURED BRANCHING QUESTIONNAIRE, THE DECODE PROGRAM INSTRUCTIONS REQUIRED BY THE COMPUTER TO DECODE THE RESPONSES TO THE RESPECTIVE QUERIES OF SAID QUESTIONNAIRE. THE CREATOR OF THE BRANCHING QUESTIONNAIRE SPECIFIES SAME, ON A CONVENIENT FORM, VIA WRITING THE BASIC INFORMATION REQUIRED BY THE COMPUTER TO GENERATE THE DATA AND PROGRAMS FOR PRODUCING BOTH THE BRANCHING QUESTIONTIONNAIRE TEXT AND DECODE PROGRAM INSTRUCTIONS THEREFOR. AFTER THE BASIC INFORMATION SPECIFIED BY THE CREATOR OF THE QUESTIONNAIRE, ALONG WITH APPROPRIATE CONTROL INFORMATION THEREFOR, IS ENTERED INTO THE COMPUTER, THE COMPUTER AUTOMATICALLY ARRANGES SAME TO FORM A QUESTIONNAIRE DATA SET, WHICH IS STORED ON DISK FILES AS SHOWN AT 17. THE QUESTIONNAIR DATA SET PROVIDES A CONVENIENTLY ADDRESSABLE COMPILATION OF THE INFORMATION ENTERED INTO THE COMPUTER. THE COMPUTER THEN ACTS TO RETRIEVE FROM THE QUESTIONNAIRE DATA SET, THAT INFORMATION DEFINED THEREIN WHICH IS BASICALLY REPRESENTATIVE OF THE TREE STRUCTURE, AND TRANSFORMS THIS INFORMATION INTO A QUESTIONNAIRE STRUCTURE TABLE AS SHOWN AT 19, WHICH TABLE UNIQUELY AND UNAMBIGUOUSLY REPRESENTS, IN A PARTICULAR TREE FORM ARRANGEMENT, THE ESSENTIAL DATA REQUIRED BY THE COMPUTER TO AUTOMATICALLY GENERATE THE DECODE PROGRAM INSTRUCTIONS. THE QUESTIONNAIRE STRUCTURE TABLE AND QUESTIONNAIRE DATA SET ARE COOPERATIVELY EMPLOYED BY THE COMPUTER TO GENERATE AN IMAGE OF THE TEXT OF THE QUERIES OF SAID QUESTIONNAIRE AS SHOWN AT 21 AND 23 AND, IN ASSOCIATION WITH THE POSITION OF THE RESPECTIVE DESIGNATED LOCATIONS OR SPOTS IN THE TEXT OF SAID QUERIES AT WHICH A MANUAL RESPONSE TO EACH QUERY IS TO BE MADE, TO GENERATE AT 31 THE DECODE INSTRUCTIONS (CALLED IMD&#39;&#39;S) REQUIRED BY THE COMPUTER TO DECODE THE RESPONSES THERETO.

and programs for producing both the branching questionnaire text and decode program instructions therefor. After the basic information specified by the creator of the questionnaire, along with appropriate control information therefor, is entered into the computer, the computer automatically arranges same to form a questionnaire data set, which is stored on disk file as shown at 17. The questionnaire data set provides a conveniently addressable compilation of the information entered into the computer. The computer then acts to retrieve from the questionnaire data set, that information defined therein which is basically representative of the tree structure, and transforms this information into a questionnaire structure table as shown at 19, which table uniquely and unambiguously represents, in a particular tree form arrangement, the essential data required by the computer to automatically generate the decode program instructions. The questionnaire structure table and questionnaire data set are cooperatively employed by the computer to generate an image of the text of the queries of said questionnaire as shown at 21 and 23 and, in association with the position of the respective designated locations or spots in the text of said queries at which a manual response to each query is to be made, to generate at 31 the decode instructions (called IMDs) required by the computer to decode the responses thereto.
